The AVMA supports the use of water-based foam as a method of mass depopulation for poultry in accord with the conditions and performance standards outlined by the US Department of Agriculture's Animal and Plant Health Inspection Service (USDA-APHIS). The following summarizes the conditions under which USDA-APHIS has approved the use of water-based foam for depopulation of poultry:
Mass depopulation refers to methods by which large numbers of animals must be destroyed quickly and efficiently with as much consideration given to the welfare of the animals as practicable, but where the circumstances and tasks facing those doing the depopulation are understood to be extenuating. Euthanasia involves transitioning an animal to death in a manner that is as painless and stress-free as possible. The AVMA currently considers that destruction of poultry using water-based foam is a method of mass depopulation and not a form of euthanasia. The AVMA supports additional research to evaluate whether water-based foam can be accepted as a form of euthanasia.
